Spin angular momenta of circular polarized photons influenced chemical reactions. It has revealed that the circular polarized light (CPL) strongly influences self-assembly of racemic CdTeNps. When light is enlightened to sample of racemic CdTe NPs, NPs separated in to right-and lefthanded twisted nanoribbons with rightand lefthanded circular polarized light (CPL) respectively which induces due to light. This is because of spin angular momenta of circular polarized photons influenced chemical reactions. It is seen that enlightening to such chemical reactions surplus both type of enantiomers which is ͂10 times higher than CPLinduced reactions. Further illumination of linearly polarize light plus assembly in dark led to non-twisted nanoribbons. The mechanism of “templation”of NPs assemblies by CPL is correlated with selective photo-activation of chiral NPs moreover clusters followed by their photo-oxidation. Chiral anisotropy interfaces translate in to chirality of the given assembled ribbons. The ability of NPs to preserve polarization information of incident photon releases new pathways for the synthesis of chiral photonic materials. It also allows for improvement understanding of the origins biomolecular homo-chirality.
